Evil Alignment plausible in IWD? (Plz no spoilers)

I haven't played this game for a decade. Can't recall the storyline. Are there any plot reasons a neutral/evil, predominantly evil party wouldn't go on these quests? I prefer selfish bastards over high-fantasy goody two-shoes, it's just my way, but I want a plausible roleplaying experience, too.

Sure, but in some cases in BG, you take on cases specifically for the good cause, no award offered or available, in fact clearly ruled out in the dialogue options. Those quests suck, or rather their prompts suck. I was wondering if any major quests were clearly pro bono publico and with no reward in sight. An evil or selfish character might have a hard time justifying taking on such trouble in such cases.

Of course, an intelligent character might consider that there must be room and opportunity for graft, corruption, embezzlement or outright theft SOMEWHERE even during the most noble of causes. Yeah, that'll do.

Pro Bono events aside from helping Kuldahar are on a per-class basis, not a per-alignment basis. Evil characters can easily justify helping Kuldahar as a revenge strike against whoever attacked them in the pass.

Yes, there's a lot of room to play the game with a motivation of "________ basically wants to destroy everyone in the north; I don't give a damn about anyone else, but *I* am someone who is currently in the north and I don't very much feel like being destroyed, so let's go put a sword through his/her/its face."

Basically, you're stuck in the same boat as all of the innocents, so it doesn't matter if you're motivated to save the innocents or to save your own skin, your actions will largely be the same either way.

Cheers for your comments, everyone. Actually, in my current game I have gone down the ostensibly good path with an evil character in one instance, for roleplaying reasons. My party leader, a Lawful Evil Champion of Myrkul, God of the Dead, and by extension Burials etc., (a paladin-esque kit from the fantastic Faiths and Powers mod), didn't approve of the halfling in Kuldahar burying the proper owner of the inn in an unmarked grave and taking over the operation. See, I COULD'VE just taken the selfish path to free lodgings in return for not telling anyone, but Myrkul would have disapproved of the halfling trespassing on his portfolio. (Heh, the halfling even called me a paladin, and he didn't mean it as a compliment!)

There are quite interesting evil/neutral/chaotic dialogue options , starting from easthaven where you have dishonest , greedy or even rude lines . A few early game spoilers on an evil party motivation:

There are dialogue options where You can take Hrotgar's quest because it leads to fortune and (from a more lawful approach) glory.In kuldahar pass there are evil dialogue options when dealing with the boy who lost his family, including an cleric line a and in kuldahar you might not wanna help them out of your good heart, but there are dialogue options with arundel where you conclude that you're stuck in the pass and your only way out is this misterious enemy
